bituminous coal. The quantity of gas obtained by the distillation of the briquettes is so small, and its content of useful by-products so immaterial, that the recovery of the by-products does not pay, and the use of all the gas obtained in heating the known ovens, intended for this purposefnoes the coking chambers and heating walls.
not insure the proper heating of the ovens.
The invention has for its object to improve heating conditions in an oven adapted for the above mentioned use, and is characterized 5 the passage of the distillation gases from theccik- H ing it through special recuperative heating chambers receiving heat from the waste gases. Said heating chambers are disposed at one side of the oven, and the vertical gas supply channels at the other side, and the preheated air for combustion is led to the ends of the heating flue ends connected to the vertical gas supply channels through special air feed channels, arranged in the heating walls and serving as recuperator chambers. Every gas supply channel may have associated with it an individual preheating recuperator chamber. The heating walls maybe subdivided into two vertical rows of horizontal heating lines. The horizontal feed channels for the preheated air of combustion then may be situated between the heating fiues.
The primary advantage obtained with coking ovens constructed in accordance with the invention, results from the fact that the flow paths through which the unpurified distillation gases pass to the heating fines are very short and comprise channels which are easily accessible from the-outside, since they are situated in an outer wall portion of the oven structure. Furthermore, since combustion in the heating walls is initiated in proximity to an outer wall of the structure,
damper regulation of the gas and air inlet openings is readily obtained.
The ovens may be provided with any usual or suitable charging and discharging means, for intermittently feeding briquettes or other material to be treated into each oven chamber at its top, and for intermittently withdrawing the treatedmaterial from the bottom of eachoven chamber. I
Further details of the invention will be described with reference to the drawings, in which:
Fig. 1 is a vertical section of the oven struc-. ture, in the longitudinal direction of the oven chambers and heating walls, on the broken line l-| of Fig. 3;
Fig. 2 is a partial horizontal section on the line 2-2 of .Fig. .1;
Fig. 3isa partial vertical section on the line 33 of Fig. 1;
Fig. 4 is a partial vertical section on the line 4-4 of Fig. 1; and
Fig. 5 is a horizontal section on the line 5-5 of Fig. 1.
The coking oven structure shown in the drawings, comprises a row of side by side oven chambers a, transverse to, and extending into proximity with, theright hand side of the structure, as the latter is seen in Figs. 1 and 2. The hereinafter described recuperative airpreheating provisions are located in, the portion of the oven structure between the left hand side of the latter as, seen in Figs'l and '2, and the adjacent ends of. the chambers 41. The gas produced by the distillationlof the briquettes in the chambers 01., enters vertical channels at, there being one such channehas showmbetween the right hand end of each chamber a. and the adjacent side of the structure. The channelsd are in communication with one another through a horizontal top flue e, adjacent the right hand side of the structure. The heating ,wallbetween each two adjacent coking chambers a, includes a vertical row of. horizlontal ..,heating or combustion flues 7c alongside, and individual, to, each coking chamber a,' and includes two side by side vertical rows of horizontal combustion. air supply fiues n (Fig. 5), between the two rows of, fines is in the wall. The heating fines is at each side of each chamber a, receive gas'frorn the channel d at, the end of the chamber, through ports regulated by damper bricks or p'artsfs, which'may be manipulated through holes in the side of the structure fitted with removable plugs w. At the same side of the .oven structure at which it receives gas mm the corresponding channel (I, each heating flue it receives preheated combustion air through ports p from the adjacent supply channel n, in amounts which may be regulated by adjustment of damper bricks or parts 8 respectively adjacent the ports p.
The air for combustion first streams through air heating, horizontal recuperative chambers m which are in communication at their right hand ends, as seen in Figs. 1 and 5, with the left hand ends of channels n. The air preheating chambers m communicating with the channels 1!. in each vertical row of the latter, are arranged in a vertical row in which they alternate with horizontal waste heat chambers r. The latter communicate at their right hand ends with the adjacent ends of the combustion flues k in a corresponding vertical row of the latter. As shown, in Figs. 1 and 2, the chambers 1 communicating with the heating fines is at the opposite side of each chamber a, discharge into the same vertical duct t, which is in communication with the said chambers T adjacent the left hand side of the structure, as seen in Fig. 2 through ports which may be regulated by damper bricks or parts 0. The products of combustion entering the vertical ducts 73, pass upward through the latter to the discharge stack. In order to improve the heat exchange between the products of combustion and the air for combustion passing through the chambers T and m, respectively, the chambers m may be provided with baflle plates 0, extending transversely to the direction of air flow as shown in Fig. 5.
